The formula for calculating the electric potential outside of a spherical conductor is V = kQ/r, where V is the electric potential, k is the Coulomb's constant, Q is the charge of the sphere, and r is the distance from the center of the sphere.
The electric potential decreases as the distance from the spherical conductor increases. This is because the electric field created by the charged sphere becomes weaker with increasing distance, resulting in a lower potential.
Yes, the electric potential outside of a spherical conductor can be negative. This occurs when the charge on the sphere is negative, resulting in a negative value for the electric potential.
The electric potential and the electric field outside of a spherical conductor are directly related. The electric field is the negative gradient of the electric potential, meaning that the direction of the electric field points towards regions of lower potential.
The electric potential outside of a spherical conductor is constant and only dependent on the distance from the center of the sphere, while the potential inside the sphere varies and is also affected by the distribution of charge within the sphere.
